Network Speed / Docker Speed

Hello,

The issue started while i was trying to know my real network speed (Wifi) and the potential need for an upgrade to Wifi 6 ...

I installed openspeed test network and got a wifi speed about 600Mbits/s from my macbook air m1.

To be sure, I tried the same from a windows VM on Bridge with a discrete IP from the server and got a 980Mbits/s up and down.

So for sure I have only a gigabit network, so I assume the connection from the VM to the server (which has another IP) is going through the router ?

I tried to validate the results by doing an Iperf from the VM to a Iperf3 docker, and got a 7Gb/s

[ ID] Interval           Transfer     Bandwidth
[  4]   0.00-10.00  sec  8.56 GBytes  7.35 Gbits/sec                  sender
[  4]   0.00-10.00  sec  8.56 GBytes  7.35 Gbits/sec                  receiver

When I doing a file transfer from the VM to the Unraid Cache, I'm getting between 800MB/s and 900MB/s , so also almost a 10Gb/s connection, saturating the M.2 SSD

This is concistent because the VM in on the host on a virtual adapter.

So but I do not understand why the Openspeedtest is limited to 1Gb/s

PS, I tried an Iperf3 from the unraid command line to the iperf3 docker, and got over 50Gb/s
